Table 3 Kappa Agreement between PROMs and electronic medical record

	Incidence of patient-report N (%)	Incidence of diagnostic code N (%)	Kappa agreement statistic (95% CI)	Sensitivity ^b	Specificity ^c
Intervention clinics (n = 329) ^a
Falls N = 318	115 (36%)	13 (4%)	0.04 (−0.01, 0.10)	0.08	0.98
UI N = 325	142 (44%)	29 (9%)	0.10 (0.03, 0.17)	0.14	0.95
Control clinics (n = 176) ^a
Falls N = 174	81 (47%)	5 (3%)	0.07 (0.01, 0.14)	0.05	0.99
UI N = 173	75 (43%)	7 (4%)	−0.03 (−0.09, 0.04)	0.03	0.88

^a Missing fall data from 11 individuals from intervention clinics and 2 from control clinics, missing UI data from 4 individuals from intervention clinics and 3 from control clinics
^b Sensitivity of a clinical test refers to the ability of the test to correctly identify those patients with the disease. Calculated by true positives/(true positive + false negative)
^c Specificity of a clinical test refers to the ability of the test to correctly identify those patients without the disease. Calculated by true negatives/(true negative + false positives)
